Improvement in amalgamators



UNITED STATES PATENT OFFICEo GEORGE C. LANGTRY AND GEORGE EMMETT, OF GOLD HILL, NEVADA.

IMPROVEMENT IN AMALGAMATORS.

Specification forming part of Letters Patent No. 123,918, dated February 20, 1872.

To all 'whom it may concern:

Be it known that we, GEORGE C. LANGTRY and GEORGE EMMETT, of Gold Hill, in the county of Storey and State of Nevada, have invented a new and Improved Amalgamator; and we do hereby declare the following to be a full, clear, and exact description ofthe same, reference being had to the accompanying' drawing making a part of this specification, in which- Figure l is a top view, and Fig. 2 a side elevation.

This invention has for its object to pulverize slime or mud containing gold and silver ores, obtained in the preparatory dressing, tailing, or the refuse part of stamped ore thrown behind the tail of the buddle or washing apparatus, or gold and silver-bearing sand; and also to separate and amalgamate the precious metals therein contained.

Referring to the drawing, a is the cup-shaped hub of the horizontal muller and amalgam ator, the same being supposed to be suit-ably secured to a vertical rotatory shaft, and to be set within such a pan as is Ordin ari] y used for the purpose. b are a series of arched openings in the sides of the cup-shaped hub, said openings alternating with fingers c, from the lower ends of which eX- tend curved spokes or shoes f, which are connected at the outer ends by a rim, d, secured to the upper sides of the shoes. The upper and lower edges of the shoes are horizontal,

while the front and rear sides of every shoe are beveled parallel to each other, the slant of each shoe, however, being in an opposite direc' tion to that of the shoes next to it on. each side. In other words, the shoes are beveled alternately in opposite directions.

Those shoes the upper corners of Whose front sides project over the lower corners pass over the pulp as the wheel revolves, and those whose lower front corners are in advance of their up per front corners scrape up the pulp from the bottom of the pan. The pulp scraped up by one shoe rolls over its top and falls into the path of the next succeeding shoe. The arched openings in the hub, and the Open spaces between the outer ends ofthe shoes below the rim, allow the currents of pulp to iiow in every direction, so as to become thoroughly intermngled with the mercury.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

The arrangement of the cup-shaped hub a,

arched openings b, curved shoes f alternately beveled in opposite directions, and the rim d secured to the upper sides of the shoes, as speciiied.
